Crab-eating Macaque
Macaca fascicularis

The Crab-eating Macaque, also called the Long-tailed Macaque with a tail as long as its body, is native to Southeast Asia.
There are several subspecies over their range.

Like other macaques, it is a social animal living in a female-dominated heirarchy with the direct descendants of the lead
matriarch taking precedence. (The individual shown above has a shortened tail.)

Also like some other macaques, the Crab-eating Macaque sits down alot and carries its own cushion.

Despite the name "crab-eating", crabs are not a key part of the diet. They are omnivores eating fruit, seeds, small birds and rodents
but do forage on beaches for shellfish, including crabs.

They have been observed using stones to crack open shellfish, molluscs and nuts.
